4 08/14/02 F 68.28 A 1 PERMANENT MAGNET GENERATOR FAILURE Summary:

Oconee unit 1 began the month of August operating at 100% power. On 08/14/02 at 0650 the unit began decreasing power and was taken off-line 08/14/02 at 0728 due to permanent magnet generator failure. The unit was placed on-line 08/17/02 at 0345. During power escalation the unit held at 30% power from 0448 to 0939 due to nuclear instrumentation calibration. The unit held at 39% power from 1007 to 1021 to add 1B bleed holdup tank to the letdown storage tank. The unit held at 55% power from 1126 to 1212 due to problems starting 1B feedwater pump, which resulted in a additional hold at 60% power from 1237 to 2028 to repair 1B feedwater pump. During power escalation the unit held at 90% power from 2208 to 08/18/02 at 0050 due to nuclear instrumentation calibration. On 08/18/02 from 0135 to 0322 the unit held at 98.5% power to place E heater drain pumps in-service. The unit returned to 100% full power on 08/18/02 at 0339. On 08/19/02 at 1306 the unit began decreasing power to remove the moisture separator reheater from service and held at 95% power from 1358 to 1733. The unit returned to 100% full on 08/19/02 at 2050. On 08/25/02 at 0802 the unit began decreasing to 22% (Cont'd)

Summary:

power and held from 1002 to 1426 to place the moisture separator reheater in-service. The unit resumed power escalation, and held at 32.8% power from 1458 to 1503 due to high hotwell pump flow. The unit held at 58% power from 1625 to 1817 due to 1B feedwater pump motor speed changer problems. The unit held at 90% power from 2004 to 2012 due to nuclear instrumentation calibration check. The unit returned to 100% full power on 08/25/02 at 2101 and operated at or near 100% full power the remainder of the month.
